Rainmaker 4 Gallon (16 Liter) Backpack Sprayer

Rainmaker 4 Gallon Backpack Sprayer for Big Beds and Greenhouse Rows The Rainmaker 4 Gallon (16 L) backpack sprayer carries enough mix to cover large beds, raised gardens, and greenhouse rows without constant refills. A manual pump builds the pressure, and the lock-on trigger keeps a steady stream going through a long pass. Four interchangeable nozzles switch between fine mist, focused stream, and wide fan. The 4 ft hose and integrated filter keep debris out of the nozzles. At about 8.3 lbs empty, it's light to carry between fills, and the padded straps spread the load once the tank is full. A Manual Pump Backpack Sprayer for Foliar Feeds and IPM Pump it up, lock the trigger, and work a row without stopping to re-pressurize every few plants. The nozzle set covers foliar feeds, protective sprays, and spot pest treatments from the same tank. An integrated filter guards the pump and nozzles, which matters most with wettable powders that can grit up a line. It measures about 17.7 by 7.2 by 23.2 inches, so it stores upright on a shelf between jobs. One trade-off: a manual pump means periodic strokes to hold pressure, unlike a battery unit that runs itself.
